석괴댐의 축조 중 내부 침하 거동 평가

초록

The purposes of this research are to analyze the internal settlement behavior of Concrete Faced Rockfill Dam (CFRD) typed ‘dam’and to evaluate the stability of the ‘ dam’during dam construction using internal settlement measurements and results of numerical analysis. The field measurements were obtained during dam construction period. The numerical analysis was also carried out for the same construction period. The numerical analysis focused mainly on prediction of stress and displacement behavior of ‘dam’during dam construction stage using input parameters obtained from laboratory tests, i.e. large triaxial tests. The behavior of ‘dam’was evaluated to be stable from comparing the results of field measurements and numerical analysis. A simple empirical equation is also presented to predict final settlement at the completion of dam construction, using settlement measurement monitored during dam embankment.
